An area of rain will erupt along the East coast from southeastern Virginia to southeastern New England Thursday into Friday.
Some beach communities right could be thoroughly drenched. A few spots could be hit with flash and urban flooding. Rain will brush some of the I-95 cities in the Northeast as well.
While cooler, less humid air continued to expand over the Northeast Wednesday, it will not be enough to prevent a new swath of rain from affecting many coastal areas.

The cool pattern, with and without rain, in the Northeast will represent a big change from the heat and high humidity from last week. AccuWeather.com RealFeel® temperatures in some areas with the rain may be more than 30 degrees lower, when compared to the heat, sunshine and high humidity recently.
Some rain is likely to fall from Norfolk, Va., to around New York City and Boston Thursday.
Dry air is forecast to chase the rain away over much of eastern Virginia, the Delmarva Peninsula and New Jersey during Friday. However, rain may continue farther to the northeast along the coast.
There is a chance of heavy rain, lasting several hours from the Virginia capes to the Maryland, Delaware, New Jersey and Long Island beaches to Cape Cod.
Farther west, the rain is more likely to be spotty from southern Virginia to Washington, D.C., Baltimore, Philadelphia, Hartford, Conn., Worcester, Mass., and Portland, Maine.
The rain is likely to stay away from much of West Virginia, western Maryland, Pennsylvania, upstate New York and northwestern New England Thursday and Friday, before returning later in the weekend.

According to Mark Mancuso, "There is a slight chance a very weak tropical system forms in the pattern along the Atlantic coast before the end of the week."
A series of systems originating from the central Plains will take a left turn along the East coast into the end of the week.
"The systems will tap into tropical moisture as they reach Atlantic waters and can bring very heavy rainfall in a narrow zone right along the coast," Mancuso added.
While the pattern favors a quick rebound in humidity levels, it does not favor extreme heat at the same time. High temperatures will tend to average below normal through the weekend.
